Continued Harassment from Ismail & Dahya

They are back to phoning me 3 to 4 times a week - twice a day - for a R50 payment!! And it's recorded on every single phonecall that I will pay it as soon as I get money. Yet they continue to call!

I have 19 (NINETEEN) phonecalls from them - listed in my call register - for NOVEMBER ONLY! (today is the 21st)

How can I make this harassment stop?!!
